This nailer is great! I was surprised at how well built it is and very light weight for extended use. I've used it to drive 2-1/2 concrete nails through 1x3 batten strips into a filled cinder block and it's monstrous. You need to fine tune the pressure so the nail doesn't drive the nail into the boards. It pairs beautifully with various lengths of corrugated concrete nails available at any hardware store.
